The hydrostatic bearing promises life and speed characteristics currently unachievable with rolling element bearings alone. In order to achieve the speed and life requirements of the next generation of rocket engines, turbopump manufacturers are proposing hydrostatic bearings to be used in place of, or in series with, rolling element bearings. The design of a hydrostatic bearing is dependent on accurate pressure in the bearing. The stiffness and damping of the hydrostatic bearing is very...

Abstract — Shape Memory Alloy - Metal Matrix Composites (SMA-MMC) are a relatively new class of the so called intelligent or smart materials. They can reach exceptional mechanical properties or even a functionalization by the use of Shape-Memory-Materials as “reinforcing”-elements. In this work a SMA-MMC consisting of an EN AW-6060 aluminum matrix and a Nickel-Titan-alloy (Nitinol) wire as reinforcing element was investigated. The composite was produced by a composite extrusion process... Topics: Smart Material, Composite extrusion, Nitinol, SM-MMC, Deformation behavior.
A preliminary investigation of a simple 5 deg conical-flow expander was made to determine the feasibility of using this type of device to increase the Mach number in the test section of a supersonic wind tunnel. The inlet-to-exit area ratio of the nozzle was that required to increase one-dimensional flow from a Mach number of 3.88 to 5.5. The Mach numbers obtained at the expander exit varied from about 5.1 at the centerline to about 5.4 near the walls. No difficulty in operation of the main...
